Troubleshooting
PTZ controls are not working or are not working properly
• RS485 wires not connected or connected using wrong polarity. Ensure
the red wire is connected to the + RS485 port and the black wire is
connected to the - RS485 port.
• Not enough of RS485 wire is exposed to make proper connection. Use
a wir
e stripper (not included) to strip off some of the wire insulation.
• Extension cables may be damaged or are not connected properly.
Check y
our extension cable run.
• PTZ protocol details are not configured in DVR. See your DVR
ins
truction manual for details.
• Multiple PTZ cameras are using the same c
amera ID. This will either
disable or affect PTZ controls. Configure a separate camera ID for
each camera (see “Setting the Camera ID” on page 22 for details).
DVR motion detection is constantly triggering
• Turn off motion detection on the channel the PTZ camera is connected
to. DVR’s use video motion detection, which means they detect motion
by looking for changes between frames (images) in the video. If the
camera is moving, the DVR will detect this as motion.
